colored after the dyeing process and also there is a marked tendency for the color to wear away and leave the material in its original shabbycondition.

' The object of this inventionis to provide an improved process of dyeing rugs, carpets and upholster in situ.

Another ob ect of this invention is to provide an improved dyeing process which will renovate or restore the color of interior cover- 320 ings.

A further object of this invention is to provide a process of dyeing carpets and upholstery which will be simple in operation and which may readily be carried out by the @6 housewife.

In the dyeing or restoring of carpets, rugs and upholster it has been found desirable to Wet thorough y the material which is to be dyed or restored before the dye is applied.

' so The material should not be soaking wet, but

it should be wet sufficiently so that a dye solution will spread uniformly therethrough upon application. In the preferred procedure the dye solution is made of substantially greater concentration than the concentration in which it is to be utilized. This concentration is so regulated that the dye solution will be diluted to a desirable extent upon mixture with the moisture or water contained inthe carpet, rug or upholstery. It is also desirable to have a small amount of a soapy material in the water utilized as a dampening or wetting agent for the material to be dyed;

hot, and then soap is thoroughly scrubbed into it with a brush. After the soap has penetrated through the material,'th e larger part of it, especially that upon the surf aeeno f the material, is removed by rubbing the material with a cloth dampened with warm water by a scraper or a squeegee with a soft, rubber contact surface which will not injure the nap. When certain materials are treated in this manner, it may also'be desirable to rub ,the jgo surface with a dry cloth to restore the nap at this point. The dfye solutionis theneppilied to the material be ore any sllhstanti ldrying takes place. Sufficientwaterxshould have been added'tothe ring so that it will now be 55 thoroughly moistened without being soaking wet. It should be possible to squeeze small quantities of water'f rom itwith pressure, V Adye soluble in cold water is preferably used: Either an acid or a basic a e may be 27.0

used and" the dye is preferably used in prb.-' portion Yof'a'bout one teaspoonful of dye'zto between one-half to two cquartsvof water. The dye should preferably never be used'in- 1 larger quantities than about. four tea'spoonfuls to one qua-rt ofwa-ter and not in smaller quantities than about one-fourth of a tea I spoonfultoxone quart of water. Acid dyes should preferably be used in greater dilution than basic dyes. The concentration of the dyesolution will vary both with the character of the dye, the material which is being dyed and the shade which it is desired to produce. The dyemay be applied-with a soft br ush and forlmly through the dampenedi material.

A method of renovating and restoring the color of interior coverings which comprises saturating the material with warm, water, scrubbing a soapy material into the covering until it becomes thoroughly saturated therewith, removing a large part of the soapy material by means of successively rubbing the material with a dampened cloth or sponge and by applying a scraper or a squeegee thereto with a soft rubber contact surbrush in greater concentration than the concentration at which it is to be utilized after having regulated the moisture content of the covering so that it will dilute the dye solution to desired extent, partly drying the material from one-quarter hour to two hours, rubbing the surface of the material with a damp cloth or sponge to remove any excess dye and finally drying the material. a
